Ok, my program suppose to convert a number(pounds) into kilograms. Two JTextField and one Button. I am not sure how to parse the value from JTextField into double but this is what I have so far. Thank you for any help. This is not working, here is the error message:
Welcome to the Ranch! Can you please UseCodeTags next time? I've added them for you this time.
Now, to the problem.
The first line does not create a text field with contents "10" but a text field that will be large enough to show 10 characters. Its content is still empty (""). To get a JTextField to show the value "10" you must a) use textField.setText("10"), or b) create it using a String value (new JTextField("10")).
That code is in the wrong place. You want that code to be executed when the user does some action. So I guess that code and your conversion code should be added to your ActionListener. That is when the user is finished typing the number they want converted, they will click on a button to get the result.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
